EASE FOE'YLAMP STANDARDS.

Application led September 16,1925, Serial No.`v56,7151.

' The invention relates to metal columns such as are used for lighting standards and more particularly to the cast-iron base which supports the column.

In a common form of lighting standards now in use, the cast-iron base which supports the column, is anchored to a cement or con crete foundation by means of anchor rods imbedded in the cement foundation and connected to the upper ends of the-base.

When van installation of such lighting Standards 'is made'the cement foundations are first poured and tlie anchor rods imbed ded therein. VvConsiderable ytime usually elapse's before the bases are installed,`these anchor rods being leftprotruding two or three feet above the sidewalk; and the same are frequently bent, which not only jinter'- feres with their usefulness but makesV the same amenace to pedestrians. v

vIn a number of casespersons have been injured by falling over Vthese rods which have become bent across the sidewalk, and clothing is frequently torn by catching upon the threaded upper end portions of the rods.y

The object of the present invention vis to provide a base ring, which may be octagonal,

hexagonal, circular, square or other shape conformingto the'shap'e of the base, this ring being placed directly'upon the cement foundation-'and secured thereto by anchor rods which are only'sufli'ciently longenough y yto extend through the ring, thereby prevent- Y ing the possibility ofA their being bent across the sidewalk and becoming a menace to per- Sons passing upon the same.

Af further object is the provision of a shoulder upon ,the base ring arranged to set within the lower open end of the cast-'iron base, each ring acting as a template which, when leveled, causes the Standard to Setabsolutely plumb and which prevents Vthe base from being shifted on the foundation in the event the same is struck by a vehicle.

The above and other objects may be attained by. constructing the `Standard in the manner illustrated inthe accompanying drawings, in which- Figure 1 is a ve-rtical sectional view of a lamp standard mounted upon the improved base ring;

Fig. 2, l, and

a section on the line 2 2 Figure Fig. 3, a detailperspective view of the inithereof extending only about vtwo inchesv above the surface of the foundation.

' AThese anchor-` rods may .be of considerably greater'diameter than the anchor rods which usually extend to the upper end of the base,

it'being usuallyvnecessary to provide com. parative-ly small anchor rods in order not to interfere with the. electric cables.V and wires or lapparatus which is vordinarily located within the base. v

vIt has been found by experience that the Y greatest corrosion in these anchor rods takes placeat the point where they enter the vcement, andr it will thus be seenthat there is a considerable advantage in using the heavier anchor rodsas 'the saine will have a. considerably longer life.

*The base ring 7, which sired shape, conforming to the, cast-iron base to be'used thereon, 'isplaced upon the cement foundation, the-openings 8 thereof receiving the upper Vthreaded 'endsrr ofV the anchorl rods, nuts 9 being placedvthereon to Secure- V*forni of anchor rods.

f The cast-iron base 10 is arranged to be Vplaced upon the ring, a shoulder 11 lspaced lfrom the outer vedge of the .ring engaging the inside of the base and properly centering the same uponvthe ring. Lugs 12 are formed upon the ring having lthe inverted T-shaped slots 13 therein to receive the heads 14 of tic-rods '15, the upper ends of which extend throughsuitable openings 16, in the flanges 17, at the top of the base.

may be 0f any de- These upper ends of the tie-rods 'are threaded to receive nuts 18 whereby the base is tightly clamped in' position upon the ring.

' be placed upon the upper end of the base in position; It. Will also bey seen'` that this surface on the foundation than ispossible in the Vusual manner and secured. thereto as by the` usual: tie-rods 20 connected at oppo# Vsite ends to the upper end of the base and 'to the cap 2l.

From the abovet willl be seen that theV present construction liasma-ny advantages over the usual practice above pointed out. TWhen installing a standard this base ring Will be the only part oliA the standard which will be placed on the streetu until the nal installation-of the standard isr 1nade.

Since it is possible to have heavier an-V chor rods with this constructiom it will be seen that a sti-*ongerv andmcre-durable structure is provid-ed, becausefthe heavier anchor rods will: not corrode as quickly as the' lighter ones.A y

Y In the event the standard isV Istruck by a vehicle,A orthe like, the base cannot lbe shifted onV the foundation as theshoulder upon the base ring holds the basel securely ring provides ay considerably larger bearing with the usual construction Wherev the bot# tom edge ofy the base restsv directly upon. the cement foundation.

This-,provides a much more rigidl installation;

Jinother very important advantage; ofthis construction is .in the ease. and readiness;fr with Which the standard: may be; repairedjv after4 an accident. Withfthe usual construe tion, having; anchor rodsv extended fromlthei cement foundation to theupper endof the,`

Vbase,y Vit has been found in many instances that" one ormorev of the anchor rods are broken", owhen the. standard is struck,` rlh-is rerpiiresv that the. entire cement founration mus-t. betornun-.and new anchor rods.y installed1 involving not only expense but considerable time to repair the same.A Y Y Where such an accident occurs during;l the day it is verylimportant to the cityor lighting company that tlie'repair Work be done immediately in order that the standard may be lighted by dark, and it is obvious that when. one of these anchor rods. is broken it is imposible.y to repair .theJ standarclf1 Within that, time lith the use of the improved base ringthe base.V Inra 2great many.. instances, espe- Y deeided. advantage.Y
